Hi,

I’m new to docker and mailcow. Mailcow is up and running behind Traefik and I have moved the vmail Volume to a zfs pool (according to this: Redirecting...

mailcow.github.io
Redirecting...
).

I have installed Nextcloud via the helper script, all went well. I now want to move the Nextcloud data folder (.data/web/nextcloud/data) to a zfs pool as well. I only want to move the Nextcloud data folder, not the whole /web folder. Any clue how I could achieve this?

Thanks in advance

  • Got it to work. After realizing that the /web Folder was mounted by the php-fpm image and not by the nginx image, it was easy to fix it via docker-compose.override.

Have something to say?

Hi Beerlao,

I am quite new on docker things and mailcow too,
i also try installing nexcloud using the helper script.

could you help me out the detail regarding docker-compose.overide

    jtdoank Sure. You have to mount the /web Folder for your PHP-FPM Container:

    Replace /path/to/your/persistent/datafolder with your local data folder (where nextcloud stores it’s user data; could be something like /var/www/html/data.

    docker-compose.override.yml

    php-fpm-mailcow:
  volumes:
          - /path/to/your/persistent/datafolder:/web/nextcloud/data:rw

      wow, thanks for the prompt reply
      let me recheck on it

      thanks alot buddy

      hahaha, trying several way but not working.
      could you help elaborate more

      🙏🙏🙏

        jtdoank Be more specific. What does “not working” mean?

          I’ve got this

          ERROR: Version mismatch: file ./docker-compose.yml specifies version 3.9 but extension file ./docker-compose.override.yml uses version 1

            jtdoank What does:

            docker-compose version
docker version
grep "version" docker-compose.yml
grep "version" docker-compose.override.yml

            say?

            Rough guess: Try setting “version” in both docker-compose.yml and docker-compose-override.yml to ‘2.1’.

              I think, i have wrong creating the docker-compose.override.yml
              let me google it how the create proper docker-compose.override.yml
              or could you inform to me link that i can create it

              cause i really quite new on docker 🙏

                jtdoank Don’t ever change the docker-compose.yml - replace it with the one from the repo. Put all your local adjustments in docker-compose-override.yml. Start with this:

                version: '2.1'

services:
php-fpm-mailcow:
  volumes:
          - /path/to/your/persistent/datafolder:/web/nextcloud/data:rw

                  Finally got working
                  Thanks alot buddy

                  version: '2.1'

services:
 php-fpm-mailcow:
  volumes:
          - /path/to/your/persistent/datafolder:/web/nextcloud/data:rw

                  need 1 space on php-fpm-mailcow
                  hahaha couple time i got

                  ERROR: In file ‘./docker-compose.override.yml’, service must be a mapping, not a NoneType.

                  but now is working and nicely done after I move all the data from /web/nextcloud/data to /path/to/your/persistent/datafolder

                  next thisngs to do is edit the php.ini

                  could you also helping edit the php.ini file
                  where exactly the file

                  btw it seems that when backup using helper script the nextcloud is not backup too isn’t?

                  did you already try to backup and restore and migrate to different server?

                    jtdoank I never used the helper script for backup. For your Nextcloud data, you only need to backup your data folder as well as your mysql tables. You can use any backup tool you want. As I’m using zfs, backups are a matter of ‘zfs snapshot’.

                    Modifying php.ini: Check mailcow/mailcow-dockerized590

                    Glad that it’s working now for you.

                        Thanks to you that it all working 🙏
                        let me check the php.ini as the link you give to me

                        beerlao backup your data folder as well as your mysql tables

                        data already, and how we can backup the mysql on docker could you help me again

                            jtdoank source mailcow.conf; docker exec -it $(docker ps -f name=mysql-mailcow -q) /bin/sh -c "mysqldump -u ${DBUSER} -p${DBPASS} --all-databases" > ./backup.mysql
